Hello fellows!I just made a fresh install of SL, and everything was working fine. Updated my package management system (don't remember the name, duh) through equo, got everything up to date through sulphur and restarted my comp.But now, my mouse has gone mad. Everytime i move it my cursor goes to the very bottom of the screen. That doesn't happens if I don't move the mouse nor if i move it through the keyboard.No, It's not a mouse problem, it works just fine on Windows.

Using 5.0 SL, 2.6.31-sabayon kernel, KDE 4.3 (it doesnt works on the other window managers too, neither on the login screen).

[Edit]Ok, I've managed to download the evdev.tar.bz2 package, extracted it, and patched it.However, I don't know how to install the directory I've patched. I did tried ./configure, ./Make and ./make install, it "did installed", but the fix didn't worked and i'm pretty sure that it's not the way it's supposed to be installed.

You'll need to do this using the Portage source package management system. I'm not on a Linux PC at the moment, but looking at the patch file (via the link 'alternative patch' on the FreeDesktop Bugzilla page you referenced), it's a single-line edit and thus easy to perform manually. Locate the source code tarball for xf86-input-evdev-2.3.2 (or whatever the latest version of evdev is) in the directory /usr/portage/distfiles/ (if it's not there already then download the tarball for the correct version of evdev and copy it to that directory), open it, find the file /src/evdev.c, apply the patch manually using a text editor of your choice and save it in the tarball. Then cd to the directory of the ebuild file for evdev (it'll probably be /usr/portage/x11-drivers/xf86-input-evdev/), create a new manifest and, if there are no error messages, merge the package. The procedure is shown below:

Then the latest ebuild of evdev will be in the directory I mentioned in my previous post. Is that the case? Have you looked to see if the ebuild file is in the directory /usr/portage/x11-drivers/xf86-input-evdev/? And what message was displayed when you entered the command to generate the manifest after you had updated the source code tarball in the /usr/portage/distfiles/ directory?

EDIT: If xf86-input-evdev-2.3.2 is not in the repository yet, but you see xf86-input-evdev-2.3.1 is there, then perform the procedure for version 2.3.1 instead of 2.3.2. I notice from the package list in the Press Release for SL 5.1-r1 that the version of evdev shipped with SL 5.1-r1 is evdev-2.3.0, so try the procedure for 2.3.1 if 2.3.2 is not in the repository yet (but you still should check what's in the directory /usr/portage/x11-drivers/xf86-input-evdev/).

Is there anything new to this issue? I have just started to install the 5.1 K on my desktop machine and get this error each time. It actually does turn me off from using the distro and maybe going for an other one... (I like Sabayon though, so let me keep my hopes that this is somehow being cared for?)

I am using a Trust Predator USB wired mouse.

Btw, this behaviour even persists after unplugging and replugging the mouse.Also, not plugging the mouse in at the boot does not have any effects on the mad behaviour.
